Experience in team management and interaction with people, with customers, suppliers and employees.

Key achievements

My more meritorious project has been my own startup project: www.simplexportal.com/en/index.html, a CMS / ecommerce SAAS platform developed from the scratch, where I demonstrate that usability and simplicity are compatible with flexibility, powerful and performance, and It's possible using standard technologies.

In last years, my key achievements have been develop large cost software for startup projects with very low resources and in short time, using technologies considered expensive, like BigData / GIS frameworks / platforms and JavaEE, using opensource tools and frameworks.

In 2001 I was the Java tech lead in the first enterprise project base in Java/J2EE in an important bank company (Santander Bank). My share in this project was recompensed with a 2 year contract in this company as Java tech lead in one of the more important departments (The Treasury Department).
